The project started after SGN won a 2013 competition run by energy regulator Ofgem, with a bid to develop remote robotic techniques to identify and seal leaking joints in live gas pipes.

A spokesman for the Institute of Advanced Motorists said: “The disruption caused by delays and road closures costs the local economy a significant amount of money, and this new technology will allow business to carry on unhindered.

“The gas industry will enhance its image no end by not having to pull up a road and subsequently repair it again.”

Scottish Road Works Commissioner Elspeth King said she was impressed with the technology.

Mrs King said: “The use of this innovation makes an improvement in the way roadworks are carried out and I commend SGN for bringing it into practice in the UK.”

A new study published last month showed Scottish commuters face being stuck in traffic jams for up to 93 hours per year.
